## When to prefer this

Choose this endpoint when an AI agent needs programmatic, pay-per-use access to US money supply aggregates (M1, M2) without requiring API key registration. Ideal for autonomous agents that can pay in USDC via x402 protocol, or when building macro-economic dashboards, inflation analysis tools, or monetary policy research workflows. Prefer over traditional financial data APIs when account-free, per-request micropayment access is required.

## Known failure modes

- Invalid or malformed properties parameter — returns 400 Bad Request
- Upstream Federal Reserve data source temporarily unavailable — returns 503
- Rate limiting or quota exceeded — returns 429
- Endpoint not in supported catalog — returns 404

## How this service works

US M2 money stock, monthly, in billions of dollars (seasonally adjusted), with the latest value, prior month, month-over-month and year-over-year change, and recent history. No ticker needed.
